JOHN L. MAUGH, OF GULF, TEXAS.

COOLING DEVICE FOR CASTING MACHINES.

Application filed June i 3,

To u]? whom it may concern Be it known that I, JOHN L. MAUCH, a citizenof the United States, residing at (lull, in the county of Matagorda andbtate of Texas. have invented certain new and useful Improvements in aCooling Device for (lasting Machines, of which the following is aspecification.

The present invention relates to a device for cooling and solidifyinglayers of liquid hot cast material. such as sulphur, by means of a gasor vapor or mixture thereof and is especially useful in conjunction Witha method and apparatus such as is described in my application filed oneven-date and also in my application filed on; Mag -10, 1921, hearingSerial Number 468223 now Patent No. 1,417,542.

The object of the invention is to bring a cooling fiuirL ordinarily air.into effective contact with the layer of cast hot material such assulphur. in order to produce quick cooling and economical use of suchcooling fluid.

A further object of the invention is to provide a device of this naturewhich will be simple and efficient in construction, reliable inoperation. comparatively inexpensive to manufacture and operate, andwell adapted to the purpose for which it is designed.

With the above and numerous other objects in view as will appear as thedescription progresses, the invention resides in cer tain novel featuresof construction, and the combination and arrangement of parts as will behereinafter more fully described and claimed.

In the drawing Figure 1 is a longitudinal vertical section through thedevice showing the same in combination with an apparatus while in use,and

Figure 2 is a transverse vertical section taken substantially on theline 22 of Figure 1 looking in the direction of the arrow.

The hot liquid sulphur is discharged upon the \velted belt 1 or upon alayer of previously deposited sulphur :2 forming a comparatively uniformliquid layer by means of the nozzles 3 which may be of any preferredconstruction and do not form a part of the present invention,

The sulphur will be cooled and solidified due to the cooling action ofthe surface upon which it is discharged and also due to the coolingaction of a stream of air passing 1922. Serial No. 565,577.

over its upper surface which is sup lied by the device about to bedescribed. n order to use such air efficiently it is caused to pass overthe deposited sulphur in a comparatively thin stream so that thoroughcontact may be established between the air and the sulphur, due to theirproximity and the air eddies caused by friction.

The device consists of a cover 4 which is suspended over the layer ofsulphur in such a manner to obtain clearance of the passage of the airbetween it and the sulphur. The stream of air is fed into such passa efrom a header 5 which will receive its supp y from the main air duct bymeans of a flexible connecting duct, not shown, attached to the neck 6.Thefheader may be fully or only partially open over the sulphur layer,but preferably the cover should extend over the header, adjacent to eachside of the sulphur layer so as to prevent to a great extent the leakageof air from the header before it has been brought into immediate contactwith the sulphur as is shown to advantage in the drawing. This header isalso preferably provided with a flexible flap 7 for maintaining contactwith a roller 8 adjacent thereto to prevent excessive leakage in thatdirec tion, this roller 8 being journalled on a shaft 9 over whichextend the hook extensions 10 as is indicated by the dotted lines inFigure 1. This roller, by making contact with the surface of thesolidified sulphur, will further prevent air leakage in a directiontoward the adjacent sulphur discharge nozzle The roller is alsonecessary to aid in carrying the air header and cover, maintaining auniform clearance between the same and the surface of the sulphur.

This roller 8 is maintained in its proper position by the guide brackets11 engaging the shaft extensions from the roller or in any othersuitable manner. It is desirable that the roller may rise or lower tomaintain contact with the sulphur as the thickness varies. The cover orheader are further supported and maintained bv bracket extensions 13which are to be carried by the roller of the adjacent cooling device,or, by a fixed support where there is no adjacent cooling device, as isthe case beyond the first nozzle header. One or more such coolingdevices may be used, as necessary. to cool the layer or layers beingdeposited. It will be noted that other fluids than air may be used forthe The modification of the invention' whi'ch I" have disclosedwith'some degree of particularity, refers to the preferredform thereo fand has been given only by way of example it being understood thatnumerous changes may be resorted to within the scope of the invention ashereinafter claimed.

Having thus described my invention What 1 claim as new is l. A coolingdevice of the classdescribed including a cover, a header at one end'ofthe cover, a duct for receiving a cooling medium passing through saidheader,

2. In a cooling device of the class de scribed, 21 cover, a header at onend ofthe cover to contain a cooling incdiu'nifa flexible flap mountedin the header, a roller iintacting with said flexible flap roliatablymounted adjacent the header. v v f 3. In combination, a cover, anal;header at one end of saidcover, a rolleiiforsnp'porting the header, andmeans for supporting the end of the cover.

t. In combination, a cover, an air header roller, guides for engagingthe shaft so as to allow the roller to be vertically adjnstzr ble, andmeans for supporting the oil'ier end of the cover,

5. In combination, a moving carrier, a roller, a cooling devicesupported on the roller in spaced relation to the carrier and a layer ofsolidified material thereon.

6. An apparatus for cooling hot liquid ma terial as it is being castcomprising a mow ing carrier, a cover, a header at one end ol' the coverto contain a cooling medium. and means forhbltling the cover and headerin spaced relation above the moving carrier.

In testimony Whereoi l aliix my signature in presence of two witnesses.
